"You asked me what cake I like, then you didn't bake me that cake, then you were upset that I expressed disappointment that I didn't get the cake I said I liked after you asked me what I like"
is a metaphor for the more abstract concept of
"you prioritize your desire to impress me over actually pleasing me, and I do not recognize the importance appreciating your efforts even when they fall short, and both of us are too self-absorbed to understand the emotional needs of the other and make compromises so we can both feel loved"
Flash drives are not a lasting medium. You'd need something like a quad-layer blu-ray, which is not cheap and has slow read speeds compared to solid state storage. Also nobody has blu-ray readers anymore. Also blu-ray publishers are tiny. Also the expense of distributing physical media.
So we've arrived back at the beginning - you can have this cake and eat it too, but you're going to have to eat the expense yourself. Imposing it upon the entire consumer market is selfish and wasteful.
